機能

Faster and smarter cloud code completion

• JetBrains code completion models for Python, Java, and Kotlin - Significantly improved the quality and reduced the latency of code completion for Java, Kotlin, and Python. These enhancements are powered by JetBrains' internally trained large language models. Enhanced locations for cloud completion invocation extend the variety of usage scenarios, while improved suffix matching ensures that the predicted code snippet correctly completes the existing code.
• Syntax highlighting for suggested code - Inline code completion suggestions now come with syntax highlighting, improving the readability of the suggested code.
• Incremental acceptance of code suggestions - To simplify the process of reviewing suggestions, multiline code suggestions are now displayed only after accepting a single-line suggestion, allowing you to review and accept code gradually. Additionally, if you don't want to accept an entire suggested line, you can accept it word by word using the same shortcut that you'd typically use to move the caret to the following word.
• Seamless interaction of all available code completion types - UX improvements have been made to better integrate AI code completion features into IDE workflows. This includes a reworked UX for multiline completion and the ability to display suggestions alongside basic IDE completions.

Enhanced in-editor code generation

• With this latest update, JetBrains IDEs now feature an improved AI code generation experience. Previously, generated code would open in a new tab. Now, it's displayed directly in the current editor tab, allowing for an immediate review of the generated content.

AI chat becomes smarter

• GPT-4o support - With the new release, AI Assistant now supports the latest GPT-4o model, bringing a boost to the AI Assistant's chat-related functionalities, such as finding and explaining errors, explaining code, and refactoring.
• Chat references and commands - Introduced chat references and commands to enhance your AI Assistant's chat experience, giving you more control over your context. Now, you can reference any symbols, allowing you to quickly indicate the context of your query and get more precise responses. Additionally, you can easily mention specific files or uncommitted local changes. Supported commands include /explain and /refactor, allowing you to quickly get explanations or refactor selected code without typing out questions in the chat.

New feature: merge VCS conflicts with AI

• When multiple contributors are making changes to the same part of the codebase, and you try to pull your changes, conflicts may arise. To avoid any issues down the line, JetBrains IDEs now provide a tool for reviewing and resolving any such conflicts. Starting from this release, the Git conflict resolution modal dialog features AI capabilities to assist with merging conflicts. After AI has done its job, you can review the merged result and either accept everything or revert the changes individually.

New feature: AI-powered command generation in the new Terminal

• Generate commands with AI directly in your IDE via the new Terminal tool window. This integration ensures you can efficiently complete command-line tasks without distraction, improving your overall workflow.

Enhanced unit test generation with AI Assistant

• Starting from this release, the Generate Unit Tests action can be invoked not only on methods but also on classes. If a class has multiple methods, the AI will automatically choose the most suitable one for testing. The latest update also includes more customization options for unit test generation.
• Customizable unit test guidelines - Users can set their own unit test guidelines by customizing the test generation prompt in the AI Assistant's Prompt Library. This allows you to add specific testing rules for Java, Kotlin, JavaScript, Go, Python, PHP, and Ruby.
• Adding test cases to existing tests - AI Assistant now supports adding new test cases to existing test files for Java and Kotlin, allowing you to generate new tests using AI.

Custom prompts for documentation generation

• The latest update to JetBrains IDEs introduces customizable documentation generation prompts. This feature allows the model to generate documentation for a selected code element and inserts it directly into the code. Users can now define the desired content of the generated documentation for different languages and specify various formatting options, such as Javadoc for Java, ensuring the documentation adheres to preferred styles and standards.

Natural Language setting

• You can now specify the language in which you want to interact with the AI chat via Settings. After enabling the Natural Language setting, the context of the current chat will be updated, and any new answers generated by the AI will be provided in the user's chosen language.

Using AI for working with databases

• The new release brings AI to a variety of database-specific features within JetBrains IDEs.
  • Get AI assistance when modifying tables - AI Assistant can now help you change the database-specific parameters of a table. Ask AI Assistant to modify a table according to your requirements right in the Modify dialog. Once AI Assistant generates the requested SQL code, you'll be able to review it in the preview pane of the dialog and then apply the changes.
  • Explain and fix SQL problems - DataGrip's code inspections detect various issues with your SQL queries before execution, which are then categorized according to predefined severity levels. The latest update integrates AI to enhance the comprehension and resolution of SQL problems. For issues with a severity level higher than Weak warning, the AI Assistant offers explanations and fixes. For better context and more accurate suggestions, you can also attach your database schema.

Enhance your writing with Grazie, now included in the AI Pro subscription plan

• Grazie, the AI writing companion for people in tech, is now included in the AI Pro subscription plan. Use Grazie to transform your thoughts into clear, well-articulated writing, with features like instant proofreading, inline text completion, summarization, translation, rephrasing, and more.
• Grazie is now available as a plugin for your JetBrains IDEs and as an extension for browsers. While there is a free version, AI Pro subscribers enjoy full volume access to the entire suite of Grazie's AI features, which is 500 times greater than the basic volume and replenishes weekly.
